Disconnecting Tilt Cylinder
Wear appropriate items, such as safety glasses and
steel-toed shoes whenever performing maintenance
work. Do not place fingers, hands or arms through
mast or position them at pinch points.
In this section you may be required to lift and block the
truck and mast or raise and lower different components
for removal and installation. Make sure lifting device
and sling are sufficiently rated to withstand the weight
being lifted. Never work under or around a truck that is
not properly secured. Refer to truck Data Plate for truck
weight information.
It will be necessary to disconnect and remove the bat-
tery from the truck, disconnect tilt cylinders from the
mast, disconnect electrical connections and hydraulic
lines. "Control of Hazardous Energy" section provides
information for performing the above procedures along
with some additional information on other procedures
dealing with truck maintenance. This section should be
read and reviewed prior to mast removal, installation
and maintenance as outlined in this section.
When the tilt cylinders are disconnected from the hy-
draulic system or from the mounting brackets, the mast
must be secured to keep the mast from pivoting to-
ward, or away from the truck.
• Move truck to a secure non-traffic maintenance
area with a level floor.
• Lower load engaging means (mast) completely. No
load on forks.
• Lockout or tagout truck as described in Lockout -
Tagout in this section.
• Chock wheels (refer to Lifting and Blocking in this
section).
• Attach a sling and lifting device to all mast top
cross braces so movement will be minimal when tilt
cylinders are disconnected.
